Heater Blower Motor Stops Running
If you receive customer reports in the above model vehicles that the heater blower motor stops running, the blower motor regulator should be replaced. The related symptoms for this condition are as follows:
1. During high blower demand, such as defrost or maximum cooling, the blower starts up and shuts off for approximately 90 seconds. The blower tries to restart and may shut off again. This cycle may repeat.
2. Manual adjustment of the blower speed and the blower shuts off for 60 seconds and then restarts.
3. Once the blower has shut off by itself, cycling the ignition off and back on may allow the blower to operate again.
4. Diagnostic fault code DTC 9460 may be present.
These conditions may be caused by a high blower output requested by the climate system and the blower regulator overload protection engaging unnecessarily. Follow the procedures below for corrective actions.
1. Replace the blower regulator as per the WIS document shown.
2. Additional procedures for 211 and 219 are shown above.
3. Following replacement, verify correct operation of the heater blower.
